VJAX-MELTING AND SEALING DEVICE.

Specification of Letters Patent.

Patented Got. 14,1913.

Application filed November 1, 1912. Serial No. 729,043.

To all whom it may concern Be it known that we, MACAIRE Foumvmn, acitizen of the French Republic, and resident of La Rochelle, France, andGEORGE T'TENRY JACKSON, a citizen of the United States, and resident ofLa Rochelle, France, have invented certain new and useful Improvementsin and Relating to ax-Melting and Sealing Devices, of which thefollowing is a specification.

This invention relates to a wax melting and sealing d vice the objectbeing to provide a device of this kind which may be adapted to melt onthe spot the fragments of wax intended to serve forsealing purposes by amore rapid, more economical, more hygienic and cleaner operation thanwhen the previously melted wax is applied to the spot to be sealed.

The accompanying drawings show several forms of embodiment of thisinvent-ion and in these drawings: Figure 1 shows a simple form ofembodiment of the device. Fig. 2 is a side elevation view of a deviceheated by a Bunsen burner. Figs. 3 and 4: are respectively a sectionaland a top plan view of a device in which the heating appliance is madeintegral with the melting device. Figs. 5 and 6 show respectively asectional and top plan view of an electrically heated device.

The dimensions of the diiiercnt devices vary in accordance with thedimensions of the seals and the number of seals which it is desired toapply one after the other.

In the embodiment shown by Fig. 1 the device comprises a mass or body 1made of metal adapted to efliciently conduct the heat, such as copper,aluminium, alloys of these netals and similar good heat conductors, thisbody 1 being intended to be directly heated by a small flame and also toplay the part of a heat storage device. The diameter of body 1 variesbetween 1 and 4: centimeters accord ing to the space of time duringwhich it is desired to keep it warm without applying heat to it. Thismass or body 1 carries a lateral extension 2 which is partly hollowedout and 1 to 2 centimeters long. It carries at its end a flared out part3 the surface of which may be slightly curved and which is heat-ed onlyby the heat arriving thereto from the mass through the extension 2. Asthis flared out par't is' that part of the apparatus which is an lied onthe wax in order to melt it, one thus; avoids the decomposition of thewax with the products of which the wax is inevitably covered and whichdecomposition would be brought about by the direct contact with theflame.

The heat conducting body 1 is provided with an extension 2, which canvbe heated quickly when it is not desired to usethe device continuously,thus necessitating the heating of the entire conducting body. The bodyis further provided with a hollowed out portion to increase theradiating surface of the heat conducting body 1. This part of theapparatus is secured as a whole to the end of any suitable metallic rodcarrying a flange or flared out portion a which is intended to favor itscooling so as not to heat the handle 5 which serves to hold it. Theother end of the handle carries the seal 6 in which the design isengraved which it is desired to press into the molten wax.

Fig. 2 shows a melting device heated by a Bunsen burner 9 provided witha by-pass 30. The melting device is placed upon a metallic carrier 7.7the height of which can be adjusted by means of an ordinary set screwpassing through the opening 8. The melting device can be slightlyshifted lengthwise in the carrier so as to bring the mass 1 either overthe burner or over the by-pass. The latter which is continuously burningkeeps the melting device at the desired temperature during the time itis not in use. The device is thus always ready for use. In case the saidtemperature has not yet been reached, one can bring the device to thattemperature more rapidly by opening the gas cock thus lighting the mainburner which can then be used for heating either the mass 1 or theextension 2.

The Bunsen burner can be replaced by an alcohol, petrol or the like lampcomprising a large burner for rapid heating and a small. burner of 2 to5 millimeters replacing the by-pass. One may also place side by side onthe same carrier several melting appliances. Tn this case a singleBunsen burner provided with as many by-passes as there are meltingdevices, will be sntlicient as a rule. It is similar with the lampswhere one may employ only one reservoir and one large burner, providedthere be as many small burners as there are melting appliances. 1

The above described device is used in the following manner: The hotdevice being on its carrier, is removed grasping the ham dle with thewhole hand, the part 8 is applied upon the wax which is thus melted;thereafter one turns the device around, and presses the stamp providedwith the seal on the molten wax. I

The sealing and melting device can be made integral with the heatingdevice so as to be heated in a continuous manner even during the timeduring which it is in use. Thus the loss of time is avoided which isexperienced by the reheating of the melting appliance after eachoperation during which it has cooled down. In order to attain this themetallic carrier 7 shown by Fig. 2, is replaced by a simple foot 10(Figs. 3 and 4E). The mass 11 which plays the part of a heat storingdevice is hollowed out laterally at 12 and is heated by the flame of aby-pass which burns at 13 at the end of a metal pipe 14 having adiameter of l to 3 millimeters and serving to supply the gas. This flamespreading out on the surface in front of it burns blue and as aconsequence does not soil the apparatus. A connecting extension 15provided with a cock 16 and positioned on the side of the apparatus isconnected by an india-rubber tube with the gas supply (not shown).

The apparatus constructed in the manner just described does not cooldown, not even during the application of the seals. However, if themelting device is cold and it is desired to use itimmediately, one canbring it rapidly to the required temperature by holding the devicevertically, the mass 11 turned upward, and by opening widely the cock16. Under these conditions, the small flame is considerably lengthenedand licks the extension 2 and the end part 3 and as the mass of these isvery small, the required temperature is very rapidly reached.

As shown by Figs. 5 and 6 of the drawings, the melting and sealingdevice can also be constructed in such a manner that it be heated, notby a flame, but by an electric current. lin'this case too, the apparatuscomprises a handle 17 carried by a foot 18, carrying also at one of itsends the sealing stamp 19 and at the other one the heating device. Thisheating device is formed by a tube 20 made of metal adapted toefliciently conduct heat, such as copper, aluminium etc., the thicknessof the walls of this tube varying from 1/10 to 2 millimeters. The tube20 carries on its free end the slightly convexly curved surface 21 whichis from 1 to 3 millimeters thick and by the contact with which it isintended to bring about the melting of the wax. Wound around this tubeis a wire having a high electrical resistance and made of German silver,manganine, etc.,the diameter and the length of which vary with thevoltage of the source of electricity at ones disposal. However, in'

order to allow of the utilization of the current furnished by townsupplies the voltage of which is generally superior to 100 volts and inorder to avoid to have to wind on the tube a too thin and too long aWire end, or, in order to avoid-to cause the private wires alreadyestablished in apartments where it is desired to make use of the meltingdevice to have to sustain a too high an amperage compared with the onefor which they were originally intended, the apparatus is connected inseries with an incandescentlamp which serves as a rheostat so that thebranch connection only receives a current of about 1 ampere; under thesecon ditions the winding can be made of a wire having a diameter of onlya few tenths of a millimeter and a length which is less than 5 meters.

One of the ends of the Wire 22 is connect-- ed with the lamp by means ofa binding post 23 while the other terminates at an insulated contact 24mounted on the handle. A switch 25 which by its binding post 26 isconnected with the pole of the supply which is not connected with thelamp, can be shifted on the contact 2 1 so as to cause the current topass through the wire 22 The windings of the wire 22 are insulated fromeach other either by sheets of asbestos paper or by any suitableinsulating enamel.

Having now fully described our said invention, what we claim and desireto secure by Letters Patent, is:

A device of the kind described comprising in combination a handle, aheat conducting body carried by one end of the handle, another heatconducting body carried by the first named heat conducting body andconnected therewith by heat conducting means, the heat conducting bodynamed in the second place being intended to be applied upon the wax tobe melted, a sealing stamp carried by the opposite end of said handle,and means for heating the said first named heat conducting body,substantially as and for the purpose set forth.

In testimony whereof we have hereunto set our hands in presence of twowitnesses.
